Touchpad Tap Function Won't Work On Laptop PC
Submitted by Sudheer on Sun, 07/27/2008 - 13:16.
Issue: The laptop PC has the PS/2 Synaptics TouchPad. The tap function or the double click function does not work out of the box on a fresh Fedora 9 install.
Solution: Add psmouse.proto=imps to the grub configuration file
Step 1: Open the grub configuration from a text editor
vi /etc/grub.conf
Step 2: Append psmouse.proto=imps to the kernel line
I am pasting the information from my computer. It may vary slightly on your computer.
Before: kernel /boot/vmlinuz-2.6.25.10-86.fc9.i686 ro root=UUID=c1c4deb3-cc72-4ce6-b76f-4c4a8d61b61e rhgb quiet
After: kernel /boot/vmlinuz-2.6.25.10-86.fc9.i686 ro root=UUID=c1c4deb3-cc72-4ce6-b76f-4c4a8d61b61e rhgb quiet psmouse.proto=imps
Step 3: Restart the computerAfter the computer restarts, the tap function should work.

Tap works, but now scrolling not working...
Thanks Sudheer!
I've managed to get Tap to work, but the scrolling function (horizontal & vertical) which previously work does not work anymore.. Do you know how to have Tap AND Scrolling to work together?
Also, do you know how to enable the middle button on the touchpad? (mine have 3 buttons). Thank you very much.
Mine:
Fedora 9 (Kernel: 2.6.26) - fresh install & update
Acer Aspire 5315 - not sure what Touchpad it has though

What does psmouse.proto=imps actually do?
Hi Sudheer,
Will this be installing the drivers?
I am newbie on linux. Please throw some more light on what this actually does?
Re: What does psmouse.proto=imps actually do?
Hi Nomad,
Adding psmouse.proto=imps to your grub configuration file does not install any driver. As the blog post says, if you have PS/2 Synaptics TouchPad, the instructions will help you get the tap function working on your laptop.
P.S: It is a solution to a particular issue.
With warm regards,
Sudheer
